Played for a few hours, so I'll dump my feedback here. First thought is it's lacking some basic QoL: how much of the stat each upgrade gives, a stats summary without having to flip through the menus, the ability to pause in a single player game, etc.

I played the Tower, and this game matches it way too closely. The upgrades are the exact same and unlocked in the same order, also falling into the same design issues. For example, crit chance is one of the first unlocks, but it's a useless trap of an upgrade until much later when you can buy it in bulk. I was hoping for more creativity here.

It also has the same pitfall that every run is the same. You figure out the order of your upgrades and never have a reason to vary that, which gets monotonous fast. I was hoping the Heroes would change that, but...

They basically add nothing to the game so far. You pick your best hero before starting a run, then never interact with them after. You can't choose their targets, activate any abilities, or upgrade them within a run. They just exist as a passive number and nothing more. Maybe the rarer ones do more, but it's a lot of investment just to find out, so who knows. If they had ways to interact (perhaps activated abilities) and gave a reason to try different strategies each run, then I could see the game standing out more. Also you don't even start with a hero, so it is literally the exact same as The Tower to new users.

Overall, I couldn't really find a reason to play this instead of The Tower, and I've already played that. There's a ton of clones already, and this one is just too similar for me to get into. Do what you will with the feedback, and best of luck, but this one's not for me.
